I was perusing the Ship list and something caught my eye that I honestly thought was a typo...
Freighter Speed: 3
Can someone explain to me how that was a good idea, much less got through testing without any blowback whatsoever? We only have so many ships to move resources at a time and therefore time is a precious resource. Not every account has Poseidon at their disposal or a Sea Archive in every town(build slots are still a premium you know) to reduce trip duration. Before Freighters came along, the slowest ship in the game was the Balloon Carrier at a meager 20. That's slow and anyone thinking of having a Navy has at minimum Poseidon, if not a Sea Archive as well for that very reason. Most combat Ships have a speed of 40 while Mortars, Rockets and Tenders have a speed of 30. I think it would be more than fair to set Freighters at that speed or at bare minimum 20, matching Carriers. It's not like we can have tons of them right away as it requires building Dockyards in every single town and upgrading them substantially to get any meaningful amount of them and considering late game upgrades require Millions, if not BILLIONS of resources, it would be preferable that we not wait an eternity for a shipment to arrive. Otherwise, your pushing rule is going to need a massive update considering how long Freighters take to do a shipment of any meaningful distance(god help people who spread out their Empire, much less Trade with Freighters...). I understand Rome wasn't built in a day, but Freighter Speed is simply dumbfounding.
Also considering the sheer volume of goods being moved around by Freighters, I'd also argue for a 4th Naval Slot to get Dual/Triple Ports and/or buffing Hermes Wonder(mirroring it after Athena or 160%/240%/400% at levels 3 to 5 respectively). Yet that's for another topic.
